About the Airtac SE125 Standard Cylinder SE125X190
The AirTAC SE125X190 is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks, delivering a substantial 6136 N push force at 0.5 MPa. Its robust 125 mm bore and 190 mm stroke provide the extended travel and raw thrust needed for high-inertia automation.
Unlike traditional tie-rod bodies, this unit utilizes a square extruded aluminum barrel that is completely flush on all sides, making it highly resistant to mechanical fouling while streamlining sensor placement. Please note this specific SKU is built without a magnet, so it cannot host CMSE or DMSE position switches without modification.

Where the Airtac SE125 Standard Cylinder SE125X190 Is Used
Heavy Press Stamping
Drives large metal forming presses where the 6136 N push force at 0.5 MPa is required to deform thick sheet metal components.
Injection Mold Ejection
Provides the long 190 mm extraction stroke and high thrust needed to reliably strip large molded plastic parts from heavy tooling.
Pallet Lifter Gate
Actuates heavy-duty diverter gates on high-capacity pallet conveyors, utilizing the 125 mm bore's maximum 1252 kgf thrust to shift loaded skids.
Is the Airtac SE125 Standard Cylinder SE125X190 the Right Cylinder?
Selecting this 125 mm bore yields the highest standard thrust available in the SE range, generating 6136 N of push at 0.5 MPa. If your application requires less force, stepping down to the 100 mm bore provides 3927 N of push, which may offer faster cycle times and lower air consumption.
Because the 190 mm stroke is substantial and the piston develops up to 1252 kgf of maximum thrust at 1.0 MPa, you must account for side-load bending on the Ø32 mm rod and utilize an external guide to prevent premature bearing wear. Remember that the field-adjustable air cushion at both ends only decelerates the piston near the stroke limits; it cannot hold a load if air pressure is lost. For position holding, explore the BSE rod-lock variant. As a true ISO 15552 cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 profile cylinders, utilizing a PT1/2 port and standard mounting hardware.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SE125 Standard Cylinder SE125X190 FAQ
The SE125X190 generates 6136 N of push force and 5734 N of pull force at 0.5 MPa. At 0.7 MPa, the push force reaches 8590 N, with an absolute maximum push of 1252 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa and has a speed range of 30-500 mm/s.
This specific SKU lacks the built-in magnet required for AirTAC CMSE or DMSE electronic sensors. Dimensionally, it adheres strictly to the ISO 15552 standard, meaning it serves as a direct drop-in replacement for any ISO 15552 profile cylinder utilizing the same 125 mm bore mounting interface and PT1/2 port.
